Ah ok, I had misunderstood the relevance of MPI and MPICH. Yes, I need
help in writing MPI programs! I don't want to write a normal C program
for a task and then convert it to work with MPI; it makes sense to
design for MPI from the start.

Thanks for the recommendation (and from Robert Brown) - I'd found these
books on Amazon when I was searching for resources yesterday, so I'll
check them out.

Has anyone written any nice MPI test programs that I could use to test
my cluster? I've been using the ones given with the MPICH2 distribution,
but it'd be good to try some others.
